Lightest 3rd Gen/Weight Reduction

I think I'm just jealous. I just read an article in "Excellence" about a fully prepped 911s track car w/ a full SCCA roll cage, 2 seats, coil-overs & boxed with a total WET weight 1830 pounds.

True no water or turbos to weight you down but with 240hp this would be one fun track car.

What is the lightest we can make a 3rd Gen?

Where is the 1000 pounds of lead in my car? I want it out

Thanks, Jeff

That's hard to believe... even the 1993 GT1 R weighed 2,094 lbs. and I doubt you could find another 270 lbs. to pull out of a purpose-built race car. The 2000 GT3 R weighed 2,447 lbs. according to Supercars.net, and then you're talking about pulling 600 more lbs. out of another purpose-built race car.

The RS America was one of the lightest street Porsche 911s that I know of at ~2,996 lbs. In fact, most of the street production Porsches weigh quite a bit over 3,000 lbs. It's ridiculous to believe that anyone could strip 1,170 lbs. from a street car, obviously. Not and leave it functional.

Unless it was repeated, I'd bet on it being a typo. If it was repeated, I'd have to bet on it being bullshit.

Jim,

Older car. Nice looking '73 911s tub. It's in May '01 "Excellence" 7 page article called "Doctor Diet - A Lightweight 911 built for club racing" built by Dr. Jim Calzia "weighs only 1,730 pounds dry, to be exact."

The whole 7 pages is about each part with cost per pound breakdown. "Total weight savings in glass alone: 30 pounds. Expense? $870, which translates to a weight savings cost per pound of $29."

I've seen the car before his last wreck at Thunderhill in Willows Ca.

Later, Jeff

ahh, sounds like he has some Lexon (or whatever that stuff is called) windows. That stuff is so damn light, it's like glass but also like plexi glass at same time but much lighter and doesn't scratch like plexi-glass does. Very expensive though I heard.

Wow. Well that's damn impressive, to say the least.

Evan (forget his last name) races with NASA in his FD w/ a peripheral port 13B N/A. He says his car is about 2200 lbs (I believe he actually said 2180 lbs), and he still has stock doors, fenders and body. He could probabaly drop another 50-80lbs w/ carbon doors, I'm guessing (don't know what the stock doors weight). Going with the full Downing Carbon bodywork, I'm sure would be good for another 200+lbs. I think that would be about the max weight reduction though...

Kevin Wyum's (2,300 lb.) car is fully gutted with a fuel cell in the back. His interior consists of a roll cage, a seat, and a Motec, basically, so it's not a street car. I'm not even sure if he has his heater any longer, but I doubt it. Definitely no A/C, no power steering, no air bags, no pop-up lights, no nothing.

This is the same car that competed in the 1996 One Lap of America, and the same one that ran 10.98 on stock twins, BTW.

Guess I was wrong... JoeD isn't the most childish brat on the forum.

What did someone steal your binky, Mr. RX-7 TT? Did someone take your bwanky? I wish you had some idea how absolutely laughable and pathetically immature you look following me around trying to get in a shot to pay me back for stepping all over your feelings. Guess that comment about not having any friends must have hurt pretty badly for you to be hanging on to your grudge this long... of course, then there was that thread where you couldn't spell "jelous" to save your life...

Remove PS, A/C, Airpump, Airbags and ABS. Dump all the cats and get a lightweight exhuast. Thats about 125-175 lbs right there.

a/c, airpump, abs, power steering, spare tire, big oem battery, twin turbos are pretty heavy comparitively. That's a start.

Go on a diet. Eat less twinkies.

Sleek light kit
Catalytic converter removal
A/C removal
P/S removal
SRS removal
Lightweight aftermarket seats
Single turbo (eliminate cast iron manifolds)
Lightweight battery
Carbon fiber hood (2-3 lbs.)
Spare tire/jack removal

Those are the "easy" options, if not necesarily inexpensive in some cases.

Problem is the 911 platform has TONS of aftermarket stuff.

My buddie's uncle in Germany owns an extremely lightweight (probably low 2000lb range) mid 80s 911 with a highly modded NA flat 6. He gets it up to 200mph on the Autobaun. Almost every single body part of that car is carbon fiber. He makes his own body parts for his shop...but...that's besides the point Point is there is tons of aftermarket for Porsches. You can find almost anything in a lightweight version for a Porsche. INCLUDING lightweight door panels which simply have a strap in place of door handles and full door panels.

You can buy almost anything and everything lightweight for a 911. With us, we have to go to nasty extremes to get rid of weight.

On a side note, my friend's 85 Carrera weighs 2650lbs

Don't feel bad, I bought my car new and the A/C still didn't work worth a damn. Ripping out the A/C and the power steering was one of the most satisfying mods I ever did. Not only was steering feadback far better, especially at high speed, but it made it a heck of a lot easier to get to the spark plugs when I still had a rotary engine.

Jim, is it really liveable not having the power steering in day to day driving. I've driven several cars without it and they were a handful around the parking lot. Can you try to verbalize the ill effects without it, I understand the advantages at speed.

If the car is moving at all, it's not difficult to turn, and I never felt like you needed Popeye Arms (tm) to move the car around a parking lot, for example.. Sitting still, it'll be difficult to turn, but all it takes is getting used to using a little motion to make the same turn, probably. I don't believe that I ever felt like I had to adapt or change my driving style, and I never once wished that I had the power steering back. It's a light car, it doesn't take that much effort to crank the wheels.

In street trim mine was 2500lbs even wet weight. That's with interior, cage, essentially full OEM interior except the bins and side plastic where the speakers were. I put normal cut black carpet over all those areas. The 2500 is also with a second fuel tank and SX pump etc. like Jim mentioned.
